SELF-LEVELING WAGON.

SPECIFQLCATION forming part of Letters Patent No." 700,102, dated May 13, 1902.

l Application iiled October 18, 1901. Serial No,` 79,160. (No model To all whom, it Wray concern:

Beit known that I, NELSON W. THOMPSON, a citizen of the United States, residing at Biglow, in the county of YSherman and State of Oregon, have inventedV new and useful Improvements in Self.- Leveling Vagons, of which the following is a specilication. v

This invention relates to self-levelin g wagons, the object in view being to provide, in connection with a wagon forfarming or other purposes, means whereby the body ofthe Wagon is adapted to level itself under all conditions, therebyobviating the danger of dumping a portion or all of the contents.

The Wagon-body is mounted upon the running-gear or truck in such manner that vwhile it is rendered self-leveling at all; times, yet it may be removed from the running-gear or truckA whenever occasion requires, thereby adapting dierent wagon-bodies to be sup` ported upon andrcarried bythe same truck.

With the above and other objects in View the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed. I

In the accompanying drawings, Figure l is a front elevationV of -a Wagon, showingthe means whereby the body isv rendered self-leveling. Fig. 2'is`a side elevation of the same. Fig. 3 is an elevation of one of the'sidebrackets of vthe wagonbody. Fig. 4 is'a similar view of oneof the bottom brackets.

Similar numerals of reference designate like partsin the several views.

Referring tothe drawings, 1 designates a pair of axles provided with the usual carrying-wheels 2, the axlesfbeing shown as connected by the ordinary reach-bar 3. Upon the reach-bar are supported bolsters 4 of ordinary construction and provided at or near tweenveach'pair of standards is mounted an arcuate guide or track 6, the inner edge of which is described on the true arc of a circle. This guideor track is bolted or otherwise securely fastened to the bolster, as shown at 7, and is also securely fastened, as shown at 8, to the standards 5. The Wagon-body 9 is mounted between the two guides or tracks 6, and in order to properly position and retain in place the wagon-body the latter is pro- Be-v vided on opposite sides with side brackets 9',

each provided with terminal lianges 10, by

means of which the bracket is bolted to the side of the body. Each bracket is further provided with a grooved and hanged guide- `roller 11, which moves on the inner edge of the track 6, the iianges of the roller embracing the track and preventing dislocation of the body. l

Secured to the bottom of the body in line with each guide or vtrack 6 is a bottom bracket 12, similar in constructiont'o the brackets 9', but 'preferablylargen The bracket 12 carries a weight-sustaining roller 13, which is tioning the Wagon-body. t

In driving upon a side hill'the Wagon-body will maintain its horizontal position notwithstanding .the fact .that the axles and other parts of the truck incline in accordance with ythe slope upon which the Wagon` is being driven. This obviates any tendency to spill ondump the load contained in the Wagonbody. At the same time the wagon-body may be removed from the wagon-truck by partially revolving the body far enough to move one of the guide-rollers 11 beyond the upper end of the track. In this Way' several bodies may be used upon the same truck.

s The parts of the Wagon not hereinabove par ticularly described may be constructed and arranged in any approved manner.

The invention is adapted for use wherever vbol'sters supported thereon and provided with standards, arcuate guides or tracks securely fastened to the body of each bolster and the In testimony whereof I affix my signature in presence of two Witnesses.

NELSON \V. THOMPSON.
